Hmm, not quite insider trading because no one person controls it, the original creator is unknown and never been found. So they are unable to really influence it, though they are estimated to be unbelievably rich by now (~2.5 billion $. 1 million bitcoins. ~800th richest person in the world).

I sold 72 Bitcoin for $12 each about 5 years ago, I probably sold 40-50 at higher prices prior to that. I didn't get back into cryptomining until the start of 2017, but I do think every now and again what those ~115 Bitcoin would be worth right now.
